[time-nuts] Improving performance of a GPS antenna...?

[EB4APL]

Hi,

Are you sure that the Oncore VP sends the right voltage to the antenna?  
This type needs 5 V and most pucks are designed for 3.3 V .  According 
to the manual the VP sends 5 V to the antenna but anyway it is easy to 
measure.

Regards,
Ignacio, EB4APL
